A method for the manufacture of a fiber reinforced plastic structure, comprising the steps of winding a continuous long-staple fiber impregnated with a liquid resin around a plurality of winding jigs until the resultant bundle of resin impregnated fibers attains a predetermined thickness; setting rings tightly in place on the linear portions of the resin impregnated fiber bundle between the jigs; and moving the tightly set rings relative to the linear portions thereby wringing the resin impregnated fiber bundle and expelling bubbles entrapped within the fiber bundle.

Method for production of fiber reinforced plastic structure

A core material for steering wheels, comprising a boss equipped with sleeves in a unitary structure, each of which sleeves has a slit in the axial direction thereof, said sleeves further being packed with superposed fiber strands; a ring portion; and spoke portions which connect said ring portion to said boss and being formed by winding and stretching continuous long-staple fiber strands impregnated with a resin to form the superposed strands within said sleeves.
